NASA astronauts Michael Barratt, Matthew Dominick, and Jeanette Epps and Roscosmos cosmonaut Alexander Grebenkin are returning to Earth after months aboard the\u00a0International Space Station<\/strong><\/a>\u00a0conducting scientific experiments and technology demonstrations for the agency\u2019s SpaceX Crew-8 mission. The four launched on March 3 aboard a SpaceX Dragon spacecraft from NASA\u2019s Kennedy Space Center in Florida.<\/p>\n

Here\u2019s a look at some scientific milestones accomplished during their mission:<\/p>\n

Revealing resistant microorganisms<\/strong><\/p>\n

NASA astronaut Jeanette Epps extracts DNA for the\u00a0Genomic Enumeration of Antibiotic Resistance in Space<\/a> experiment, which surveys the station for antibiotic-resistant organisms and sequences their DNA to examine adaptations to space. Results could support development of measures to protect astronauts and people in buildings and facilities on Earth, such as hospitals, from resistant bacteria.<\/p>\n

Brain organoid models<\/strong><\/p>\n

NASA astronaut Mike Barratt processes samples for\u00a0Human Brain Organoid Models for Neurodegenerative Disease & Drug Discovery<\/a>. This investigation uses human brain organoids created with stem cells from patients to study neuroinflammation, a common feature of neurodegenerative conditions such as Parkinson\u2019s disease. The organoids provide a platform to study these diseases and their treatments and to potentially address how extended spaceflight affects the brain.<\/p>\n

Bioprinting human tissues<\/strong><\/p>\n

Tissue samples bioprinted in microgravity are higher quality than those printed on the ground. NASA astronaut Matthew Dominick processes cardiac tissue samples for the\u00a0Redwire Cardiac Bioprinting Investigation<\/a>. Results could advance the production of organs and tissues for transplant and improve 3D printing of foods and medicines on future long-duration space missions.<\/p>\n

Growing better drugs<\/strong><\/p>\n

NASA astronaut Mike Barratt works on\u00a0Pharmaceutical In-space Laboratory \u2013 02<\/a>, which uses the station\u2019s Advanced Space Experiments Processor to study how microgravity affects the production of various types of protein crystals. The ability to produce better crystals could lead to manufacturing improvements and new applications and better performance for pharmaceutical compounds, potentially providing more positive patient experiences.<\/p>\n

Alloy solidification<\/strong><\/p>\n

NASA astronaut Jeanette Epps works on\u00a0Materials Science Lab Batch 3a<\/a>, two projects investigating the solidification of metallic alloys in space. Insights gained could help improve alloy solidification processes on the ground, supporting the development of materials with superior chemical and physical properties for applications in space and on Earth.<\/p>\n

Fueling the flames<\/strong><\/p>\n

The\u00a0Solid Fuel Ignition and Extinction- Growth and Extinction Limit<\/a>\u00a0investigation determines how fuel temperature affects material flammability. This image shows the fuel surface during a burn (the black part of the sphere) and the distance traveled by the flame (blue). Results could improve researchers\u2019 understanding of fire growth and inform the development of optimal fire suppression techniques to protect crews on future missions.<\/p>\n

Very long-distance calls<\/strong><\/p>\n

NASA astronaut Jeanette Epps wraps up an\u00a0ISS Ham Radio<\/a>\u00a0session on April 10, with students in Italy. The program connects students and enthusiasts with astronauts in space via amateur radio. Participants study space, radio waves, and related topics to prepare questions before their scheduled call.<\/p>\n

Student robotics competition<\/strong><\/p>\n

For\u00a0Astrobee-Zero Robotics<\/a>, students compete to have their code control one of the space station\u2019s Astrobee robots. The experience helps inspire the next generation of scientists, engineers, and explorers. NASA astronaut Mike Barratt works with the Astrobee robot named Bumble during operations for the project.<\/p>\n

Immune function in space<\/strong><\/p>\n

NASA astronaut Jeanette Epps prepares samples for\u00a0Immunity Assay<\/a>, a study of how spaceflight affects immune function. Previously, astronaut immune function could only be examined pre- and postflight, but a newly developed assay allows for testing during flight. This capability provides a more precise assessment of the immune changes that happen in space.<\/p>\n

Getting weighed in weightlessness<\/strong><\/p>\n

The\u00a0Space Linear Acceleration Mass Measurement Device<\/a>\u00a0<\/strong>calculates a crew member\u2019s mass based on Newton\u2019s Second Law of Motion, which states force equals mass times acceleration. NASA astronaut Matthew Dominick performs maintenance on the device, used in support of multiple NASA and ESA (European Space Agency) investigations on how spaceflight affects the body.<\/p>\n

Satellites for science<\/strong><\/p>\n

NASA astronaut Mike Barratt prepares for the Nanoracks Cubesat Deployer Mission 27on April 16. The mission deployed seven research satellites: a reflectometer to measure\u00a0sea ice<\/a>, tests of\u00a0telemetry instruments<\/a>\u00a0and\u00a0solar cells<\/a>, a hyperspectral\u00a0thermal imager<\/a>, a gamma-ray burst\u00a0detector<\/a>, a new\u00a0remote sensing<\/a>\u00a0technique, and a\u00a0magnetic field<\/a>\u00a0measurement test.<\/p>\n

Remote-controlled robots<\/strong><\/p>\n

NASA astronaut Jeanette Epps remotely manipulates a robot on the ground for\u00a0Surface Avatar<\/a><\/strong>. The investigation tests system ergonomics, operator response to feedback, and the potential challenges for actual orbit-to-ground remote control. Such operation is an important capability for future exploration missions to the Moon and Mars.<\/p>\n
